Abstract
The invention relates to a steering linkage system for a semitrailer, wherein the semitrailer is connected with a tractor through a swan-neck part; the swan-neck part is arranged on a tractor through a tractor saddle; the steering linkage system comprises a traction pin plate rotation mechanism, a first oil cylinder, a second oil cylinder and a steering mechanism which are matched with the tractor saddle; the traction pin plate rotation mechanism is arranged on the swan-neck part of the semitrailer and is connected with a piston of the first oil cylinder through a connecting rod mechanism; the first oil cylinder is communicated with the second oil cylinder; and the steering mechanism is arranged on a wheel main shaft of the semitrailer; and the steering mechanism is connected with a piston of the second oil cylinder. With the adoption of the steering linkage system for the semitrailer, the labor intensity of a driver can be reduced, and the controllability of the vehicle can be greatly increased to easily drive in a complicated road.
Description
Technical field
The present invention relates to a kind of superimposed trailer system, especially relate to a kind of superimposed trailer linked steering system.
Background technology
Superimposed trailer is that axletree is placed in after vehicle's center of gravity in the time of the even stand under load of vehicle, and the trailer that level or vertical power can be delivered to the hookup of tractor truck is housed.Itself is unpowered, needs to rely on other vehicle tractions to travel, could the normal motorless on-road vehicle of one using.Be mainly used in carrying personnel, goods or other special purposes.
Existing large-scale semitrailer, trailing wheel does not have turning function.Because trailing wheel can not turn to, in the time that Vehicle Driving Cycle arrives section, sharp turn, will encounter and turn to a difficult difficult problem, even can cause the unpassable consequence of vehicle.Will limit like this range of use of superimposed trailer, increase the logistics cost of goods.
Summary of the invention
The deficiency existing in order to overcome prior art, the invention provides a kind of superimposed trailer linked steering system.
A kind of superimposed trailer linked steering system, described superimposed trailer is connected with tractor truck by gooseneck portion, described gooseneck portion passes through tractor truck saddle install on tractor truck, described linked steering system comprises the traction pin plate rotating mechanism, the first oil cylinder, the second oil cylinder and the steering hardware that coordinate with tractor truck saddle, described traction pin plate rotating mechanism is arranged on the gooseneck portion of superimposed trailer, between traction pin plate rotating mechanism and the first oil cylinder piston, be connected by connecting rod mechanism, the first oil cylinder and the second oil cylinder are connected by oil pipe; Described steering hardware is arranged in superimposed trailer Wheel shaft, and steering hardware is connected with the second oil cylinder piston.
Preferably, the connecting rod mechanism of stating comprises the first lever and pull bar, the first lever is fixed on gooseneck portion by a middle part fulcrum, the first described oil cylinder quantity is two and is symmetrical arranged along superimposed trailer longitudinal centerline, the first lever two ends are connected with first oil cylinder piston respectively, pull bar one end is fixed on first lever one end, and the other end is fixed on traction pin plate rotating mechanism.
Preferably, described steering hardware comprises steering swivel and the piston crank mechanism being connected with steering swivel, and described the second oil cylinder piston connects steering swivel by piston crank mechanism, and steering swivel connects wheel stub.
Preferably, described piston crank mechanism is connected with the second oil cylinder piston by the second lever, and the second lever is fixed on semi-trailer frame chassis by a middle part fulcrum; The second described oil cylinder quantity is two and is symmetricly set on superimposed trailer longitudinal centerline both sides, and the second lever two ends are connected with second oil cylinder piston respectively.
Preferably, the middle part fulcrum of the first described lever or the second lever is positioned on superimposed trailer longitudinal centerline.
The present invention, by semitrailer axle is redesigned, makes it become the axletree that turns to that can turn to; Increase oil circuit control part simultaneously, adopt fluid pressure linkage technology, make the steering angle of tractor truck and trailing wheel keep coordinate synchronization, so just can easily tackle some narrower curved road surfaces, improved the degree of utilization of superimposed trailer.
The present invention can reduce the labour intensity of chaufeur, makes can handlingly greatly strengthening of vehicle, can easily tackle travelling of complicated highway section.
